Sunday Lake

Sunday Lake (Snohomish County) is located north of the Stillaguamish River. The 40 acre lake has an average depth of only 8 ft. Thick growth of aquatic plants limits some types of recreation on the lake, but the plants also provide habitat and take up nutrients that could otherwise intensify algae blooms. Algae blooms can occur during the summer months and the lake is occasionally posted with warnings to avoid water contact.
